I'm with Woogeroo ... those quick-change joints can do some pretty stupid things!
They forgot to put the plug back in on my buddy's rear end (no pun intended) ... these guys aren't mechanics and they don't care about the job they're doing (usually).
I'd never trust my truck to such places. Even pro mechanics -- I always inspect any job done on my truck when I get it back home, and I always find myself fixing something a mechanic did!
